The demonstration lighting system was driven by a hydroelectric generator that produced 500 volts AC, which was then stepped down to 100 volts to light incandescent bulbs in homes and businesses. That same year, Westinghouse founded the " Westinghouse Electric & Manufacturing Company "; [ 20 ] in 1889 he renamed it the "Westinghouse Electric ...
U.S. patent 2,475,841 was issued on July 12, 1949 – Automatic refrigeration system for long-haul trucks. U.S. patent 2,475,842 was issued on July 12, 1949 – Starter generator. U.S. patent 2,475,843 was issued on July 12, 1949 – Means operated by a starter generator for cooling a gas engine.
He used the system to light offices and stores along the main street of Great Barrington - the location of his West Avenue family home. Stanley's transformer design became a prototype for future transformers, and his AC distribution system formed the basis of modern electrical power distribution.
1891 – built world's first industrial AC system (Ames Hydroelectric Generating Plant) 1893 – supplied electric lights and power for World's Columbian Exposition and generators for Gettysburg Electric Railway; 1893 – hired Bertha Lamme Feicht, the company's first female engineer; 1894 – transportation Division (rail equipment) founded [38]
German scientist Otto von Guericke invented a device that creates static electricity. This is the first ever electric generator. 1705: English scientist Francis Hauksbee made a glass ball that glowed when spun and rubbed with the hand 1720: English scientist Stephen Gray made the distinction between insulators and conductors. 1745
The three also invented the modern power distribution system: Instead of former series connection they connect transformers that supply the appliances in parallel to the main line. The first demonstrative long-distance (34 km, 21 mi) AC line was built for the 1884 International Exhibition of Turin, Italy.
The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s: arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...
Founded by Robert Kern in 1959, the company soon began producing portable generators for Sears, Roebuck and Co. under the Craftsman brand. During the 1970s, Generac expanded its offerings in the portable and recreational vehicle markets, and in the 1980s the company entered the commercial and industrial markets with its backup power generation systems.
